Because the bottom frame plate is used as a power distribution board, I need some kind of insulation between the board and the frame or else it will light up as a christmass tree (at least for a second or two ) when I connect the battery.
On earlier frames, I covered one side of the double sided epoxy print with another layer of epoxy but that added too much weight to the frame. For this frame, I wanted something more subtle. So now I just cover the area where the frame tube touches the bottom plate.

First off, cut some strips of the 0,3mm epoxy.

And glue them to the frame plate.

After cleaning up and sanding, this is the result.

I think next time I use some double sided tape to hold the isolation in place. saves a lot of time and some cleaning up.

Next are the arms, probably the easiest parts because I made up a drilling jig for the holes on both sides.
The only thing to do is determine how long they have to be.

Left side is the frame side, right side is the motor side.

To determine how lang the arms had to be, I laid down four arms on the top frame and placed two props on top of the arms.
I slided them just far enough outwards until there was about 2cm between the tips of the props.
